SELFSEALIl lG-JAR OPENEB Application filed March 3, 19241 Serial No. 696,635.

To all as "m it Hm z cmtcemw B it. known that l GALLE l. JACUBSEN, on of the United States, residing at in the county of Coos and State o 1 )ti, have invented certain new and use'il Improvements in SelfiSealing-Jar (lpeners; and I do declare the following to i a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to lll'lPlOVQZIiGiltS in devices for removing the caps of jars and has reference more particularly to such a device intended primarily for removing the caps from what are commonly known as self-sealing jars.

The object of the invention is to provide an extremely simple and inexpensive device of the class set forth, yet one which may be very easily used and will quickly remove the cap ithout any danger of injuring the jar.

lVith the toregoing in view the invention. resides in the novel subject matter hereinafter described and claimed, the description being sup' 'ilen'iented by the accompanying drawing.

if igure 1 is a perspective view of a jar opener constructed in accordance with my invention.

Figure :2 is a fragmentary plan view.

Figure 3 is a side elevation showing the manner of initially applying the device to a jar cap to be removed.

Figure 4 is a vertical sectional view showing the manner of operating the device to pry the cap from the jar.

Briefly described, the invention comprises a lever having a prong which is adapted to be forced through a jar cap to he removed, said lever being provided with a fulcrum adapted to have extended hearing upon the cap. Thus, by first holding the device in a substantially vertical position and forcing the prong through the cap and then swinging said device until the fulcrum contacts with the cap, downward prying upon the lever will quickly and easily remove the cap from the jar. The device also by preference includes one or more fingers adapted to engage the edge of the cap when initially applying the device thereto, so as to properly position it and insure that the prong shall be forced through the proper part of the cap. A

str cted to the exact details shown.

rm numeral 1 designates an elongated handle whose front end carries a plate 2 which is disposed at an obtuse angle thereto, said plate and handle jointly forming a lever. I prefer to provide the rear end of the plate 2, with an integral shank 3 which is driven into the front end of the handle 1., said handle being reinforced around the shank by an appropriate ferrule it its opposite edges, the plate 2 is provided with forwardly extending fingers 5 which are disposed in a common plane and are preferably in the same plane with said plate while between said fingers, the front end of the plate is provided with a laterally extending tongue 6 whose free end formed. with one or more prongs 7 which are laterally spaced from and substantially parallel with the fingers 5. Behind the tongue 6 l have shown a horizontally elongated fulcrum block 8, (preferably formed of wood), said block and the plate being secured together by suitable fasteners 9. The block 8 extends transversely of the plate 2 and is preferably of a length to contact with a cap, substantially throughout the diameter of the latter.

In using the tool, it is applied to the cap as shown in Fig. 3. with the plate 2 in a vertical position and the fingers 5 engaging the the edge of the cap. Then, the device is forced downwardly so that the prong or prongs 7 pass through the cap. The entire device is then swung horizontally until the fulcrum block 8 rests upon the cap and further downward forcing of the handle 1, will then effectively pry the cap from the jar without danger of injuring the latter.

ikS excellent results may he obtained from the details disclosed, they may well he followedi but within the scope of the invention as claimech numerous modifications may be made.

I claim:

1. A removing device for metal jar caps comprising a lever provided with a pair of laterally spaced forwardly extending fingers disposed in a common plane and also provided with a tongue between said fingers extending laterally from said plane, the free end of said tongue having at least one prong substantially parallel with said fingers and terminating in rearwardly spaced relation therewith, said prong being adapted to be forced through a jar cap when said fingers are disposed vertically against the peripheral edge of such cap, and a fulcrum carried by said lever behind said tongue and fingers, said fulcrum extending transversely of the lever and projecting oppositely therefrom to extend substantially throughout the diameter of the cap.

2. A self-sealing jar opener comprising a lever having'a plate-like front end provided With a pairof laterally spaced forwardly extending fingers disposed in a ed to be forced through a 'jar cap When said fingers are disposed vertically at the edge of such cap.

'3. A structure'as specified in claim 2; to-

gether with a fulcrum carried bysaid plate to rest on the jar cap.

In testimonywhereof I have hereunto afiixed my signature.
